Lacrimal canalicular duct scarring in patients with lichen planus.

Background: Lichen planus (LP) is a mucocutaneous inflammatory disease that affects multiple sites, including the skin, oral cavity, vulva, and vagina and can result in scarring and stricture formation. It has also been shown to cause lacrimal canalicular blockage in a series of patients attending an ophthalmology clinic. We describe a cohort of women with vulvovaginal LP who also had signs of lacrimal canalicular scarring on examination.
